So far so good with the airpump modification to the tank. I have added some photos below for anyone else having pH problems. I attached the airpump in the rear section using a sticky pad because it means I can put the lid and back panel in place like normal.

Hi Spongebob! Thanks for your post!That's great that you came up with your own solution to tackle with the pH issue. This kind of voice from the customers definitely helps us when it comes to developing our new products. Thank you very much!

Just an update, the jellies are doing really well and growing fast! I did notice that when I went away for a few days and the bubbler was turned off the health of the jellies went down dramatically. When I got back the jellies were looking really sick! I turned the bubbler back on and within 24 hours the jellies were looking good again. I guess this shows how susceptible jellyfish are to pH swing!

could you take a picture of the back of the tank with the covers on so I can see how the wires come out?Due to the unique shape of the tank I am trying to figure out how to display it in my home while hiding the wires/tubes.

Although last time I posted that my jellies were recovering from the 5(ish) days with the air bubbler was off three of the jellies didn't actually make it. They seemed to start pulsing again and looking better soon after I got the bubbler running again but they slowly fell apart over the next few days. I would recommend anyone keeping jellies to keep a close eye on pH. I also siphoned up half of one of the remaining jellies about a week ago and he didn't make it

I now have 8 jellies in the tank (I may get a few more when they become available). They are all growing but there is a big variance in size between the smallest which is about the same size as when I got them at about 3" to the largest which probably measures almost 6".

Very little maintenance, my procedure is more or less as follows:[list=]Feed once or twice a day by mixing a few pinches of jelly food into a bowl of tank water and just dumping it inClean the sponges under a tap once a weekScrub the inside of the tank once a week with a soft spongeTop up when necessary (around once a week because the tank doesn't lose much water with the lid on)I do a water change of about one bucket every 2 weeks basically because I use old water from my reef tank and that is how much water I remove form there every two weeksThe one thing that is quite labour intensive is siphoning the bottom of the tank, being white acrylic any excess food shows up on here and is very obvious so I generally siphon this at least once a day about an hour after I feed. The way to get around this I guess would be to feed live baby artemia but I don't have time to hatch it my self so ill just stick to siphoning[/list]

I'm using the jellyfish food made by cubic to feed the jellies. Ill try and get some more images when I get chance.

I am trying to decide if I want to keep my order for the cubic or not. The vender here for North America stated it would be here in about 4 weeks. 3 weeks later he said it just shipped and was on it's way. So another 4 weeks. His email that he last sent said I could cancel the order for a refund but the ton was weird and kinda flippant. Really thinking about bailing on this tank. Would like to try another vendor but none else so far in NA.
